DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a button mounting structure, and more particularly to an operation button mounting structure installed on a side surface of a housing of a portable radio or the like.

[0002]

2. Description of the Related Art FIG. 4 shows a conventional button mounting structure. In this figure, the button 51 of the portable wireless device has the button head protruding outside through the through hole on the side of the case 53,
A small printed board 55 having a diaphragm and a pin connector 54 attached to the inside thereof is attached to a mounting groove portion 53a on the inner surface of the case 53.
And inserted. A main printed circuit board (not shown) is connected to the pin connector 54 from above, so that the operation of the button 51 is transmitted. Also, a wall 53b forming a groove portion 53a on the inner surface of the case 53
Thereby, a necessary reaction force can be obtained when the button is pressed.

[0003]

SUMMARY OF THE INVENTION However, the conventional
In the button mounting structure, if the width of the groove portion 53a is increased, the button
To reduce the operation feeling when pressing the button 51, reduce the width.
Insert the small printed board 55 into the groove 53a.
When the pin connector 54 is
It is difficult to install
Was.

[0004]

An object of the present invention is to solve the disadvantages of the prior art.
And especially the relative distance between the button and the pin connector
Can be set relatively large, and button mounting work
To provide a button mounting structure that can facilitate
And there.

[0005]

SUMMARY OF THE INVENTION The present invention provides a button mounting hole provided in the side of the case such electronic devices, the button
A groove-shaped locking portion is provided on both sides of the mounting hole, and both ends of the plate are slid into the groove-shaped locking portion so that a button can be mounted between the plate and the case . And grooved
The locking parts protrude inside the side of the case and face each other
It is composed of two sets of ribs and both ends of the plate are bent.
Bent to form a recess in the center, the button and plate recesses
With a diaphragm in which one end of the flexible printed board is interposed between the parts , the other end of the flexible printed board is extended a predetermined length into the case and a pin connector is connected, and the like is adopted. This aims to achieve the above-mentioned object.

[0006]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view showing the button mounting structure of the present embodiment viewed from the inside, FIG. 2 is an exploded perspective view showing the state of the button mounting structure viewed from the outside, and FIG. 3 is a perspective view showing the assembled state. FIG. In these figures, in a case vertically divided into two parts by a case 3 and a cover (not shown), grooves ( grooves) are formed on the inner surface of the case 3 on both left and right sides of the button mounting hole 3b.
A rib 3c of Jogakaritome portion) L-shaped and provided so as to form a 3a and reverse L-shape, a short straight ribs 3 on the inside
d is provided. Both ends 6a of the sheet metal plate 6 are slidably inserted into the groove portions (groove locking portions) 3a so as to be fixedly held in a direction perpendicular to the case side wall and in a longitudinal direction of the housing. I have.

A diaphragm 2 is attached to a surface of the flexible printed board 7 disposed between the button 1 and the plate 6 in contact with the back surface of the button 1. A part of the lower end of the flexible printed board 7 is placed in the case. It has a shape elongated by a predetermined length, and after being pulled out from the lower part of the plate 6,
The pin connector 4 is connected to the tip.

Next, the mounting operation of this embodiment will be described.

The head 7 a of the flexible printed board 7 is sandwiched between the button 1 and the plate 6, and both ends 6 a of the plate 6, which are left and right bent portions, are grooved (groove-shaped locking portions) 3 of the case 3.
a and slide it in from above to fix it.
Next, the extended portion 7b of the flexible printed board 7
Is installed at a predetermined position in the case 3, whereby the mounting can be completed.

According to this mounting structure, the button 1 is
There is no obstacle such as pin connector 4 when pushing
It can be easily pushed in. Further, by extending the flexible printed board 7, the pin connector 4 for connection to the main printed board (not shown) can be set at an arbitrary position in the housing. Also, by connecting or integrating the wiring by the flexible printed board 7, the connection to the main printed board can be made at one place without increasing the number of pin connectors 4.

[0012]

As described above, according to the configuration of the present invention, the groove-shaped locking portion is projected to the inside of the side surface of the case.
It comprises two sets of ribs facing each other,
Both ends of the plate are bent to form a recess in the center, a diaphragm connected to one end of the flexible printed board is interposed between the button and the recess of the plate, and the other end of the flexible printed board is inserted into the case. And a pin connector connected to it, and the button pressing force is supported by a sheet metal plate, so that only the both ends of the bent plate are groove-shaped locking formed in the housing.
The pin connector for connection to the main printed board is extended from the flexible printed board and arranged away from the button mounting part, so that it can be inserted into the groove inside the housing. It is possible to provide a button mounting structure having an unprecedented superior effect that the obstacle is eliminated and the workability of assembly is improved.
